Gingrich releases his tax return as Romney faces criticism

WASHINGTON — Republican presidential candidate Newt Gingrich owed $613,517 in federal taxes in 2010 on more $3.1 million in income.

Tax returns released Thursday evening show the former House speaker owed roughly 31.6 percent of his adjusted income in taxes, giving about 2 percent to charity. Gingrich took aim at rival and multimillionaire Mitt Romney this week for paying only 15 percent.

Personal financial disclosure forms filed last summer show Gingrich is worth more than $6.5 million. He reported at least $500,000 in assets from Gingrich Productions, his media company that produces books and films.

The election is taking place during a critical time in the American economy, when voters say jobs are among the most important issues in deciding whom they want in the White House.
